INDEX OB DISPLAY FRAME.

To r/Z l/fzo//i f 'muy {foncer/i "-Be it known that i. Janes ll. lhNn,Jr., aicitij/.en ot" the Ynit'ed States. and resident 'otNorthTonawanda, in the count) of Xi- S'agara `and tate`ot' New York, have in-.'ve-nted newand uscl'ul Improvements in Iiidex or Display iframes, oiwhich the tol,A Alowing is a speciicaton. l

AThis invention relates to index or display d-evi 'es oi" the kimlhaving a series of' stiti' irames or leaves hinged to a support.,and-itsolfiject isl to provide means wherebyv the frames; or leaves mayhe opened wide and iiat relatively to each other. notwithi'fstaiidingthe frames or leaves are numerous` v'and crowded and are stiti' andinflexible. This is accomplished'hv the use of a hinge. 'having twopivoted axes connecting each i fame with the common support, as herein-'other matter. Each display framecarries at its inner edge a pair o tpivot .pins or hooks e, one at thetop and one 'at the botv `Between eachdisplay frame and the` supiport, is an intermediate frame pivotallyconnected at its inner edge to the support and at its outer edge totheleat1 or panel. Each intermediate frame, as' herein shown,con'iprises a pair of hinge members f, f, one' at the top and oney atthe bottom, and

a brace, preferably vconsisting of a plate or h members bar g,-1'igidlyuniting the `hinge are preff fj The two hinge members 50 pivot pin 7i atits inner end, to engage one of the sockets c voi the support, anda-soeket 'i at its outer Aend lto receive the pivot pin c of thevdisplay frame 55- .The intermediate frame is readily removfSpecification of Letters Patent.

ahle t'rom the support b v merely lifting the pivot pins /i out, ot' thevsockets c, and the display frames are similarly removable trom theintermediate. frames. Thus the corres|iondingr parts areinterchaiigeablc. the intermediate frames may he applied 'to index o1'display devices already in use, and the intermediate frames and displayframes may be applied tosupports ot' various sizes and shapes; for itwill he understood that the invention is b v no means limited to thecircular iorm of support shown.

' ln a device ot this type, using stitiA and inficxihle leaves hingedclose together it is impossible to open out two adjacent leavessuilciently wide andv fiat to. secure the maximum of convenience andfacility in using the' device. But with the doable pivot hinge of thepresent invention a much wider opening of the, leaves is possible. Asthetop and bottom'hinge iiieinhers areI rigidly con-v nectcd the device asa whole loses nothing `1n rigidity; the intermediate yframes may beeasily` applied to index and display devices now in conin'ion use;v andall the parts heing relnovable the intermediate frames may be removedand the display Jframes directly mounted on the support, it'lso fewleav'es are used as not to interfere with their wide opening.

l claim: v

1.. In a deviceof the el'iaraeter described, a support, a series otStiti' display trames, a series of rigid intermediate frames eachconsisting `ot" Tipper and lowerhorizontal hinge harsrigidly connectedby an upright bar, and pin and socket connections pivotally connectingthe hinge bars of said interi'iie'diate frames at their inner ends tothe-support lto swing freely` without axial movement and at' their outerends to the several display frames, vsaid `intermediate frames being.detachable both from `said support and from sa'iddisplay frame withoutdisti'lrhing theparts of said support or of said interi'nediate frames.

2. In a device of the character described,

'a support'havinga series of pivot pin sockg ets at top 4and bottoni, aseries of intermediate frames each having a pivot pin aty top' andbottom arranged in an. axis neiir the inner edge or said frameand'engaging a :pair ot said` sockets, each intermediate.`

frame also having a Socket at top and' bot:

toni /arranged in an axis near the outer edge of said frame, and aseries of stiff displat frmnes each having a pivot pin at top or displaydevice of the character described,

comprising :L pair of hinge members spaced apart, each having e pivotpin at one end Signed by me at North Tonawanda, New
